脑海绵状血管瘤的诊断及手术治疗的临床分析
临床研究脑海绵状血管瘤的诊断及手术治疗的临床分析牧仁内蒙古赤峰学院附属医院,内蒙古 赤峰 024000【摘要】目的:研究脑海绵状血管瘤的诊断方法,采用手术治疗的临床效果。
方法:选取2018年11月至2020年11月本院收治的脑海绵状血管瘤患者60例,对患者进行CT和MRI进行临床诊断,所有患者均接受了手术治疗,总结分析手术治疗后的临床效果,采用卡氏评分指标对患者手术前后的功能状况进行评分比较。
结果:通过CT和MRI进行临床诊断,脑海绵状血管瘤可发生在脑内任何部位,其中额叶11例、颞叶12例、延髓15例、小脑半球10例、右基底节区12例,CT平扫为稍高密度影,部分病例可见钙化灶,注药后大都无强化,急性出血患者34例,非急性出血患者26例;通过手术治疗,患者的临床症状得到明显缓解,卡氏评分与手术前相比较得到明显的改善。
结论:临床对于脑海绵状血管瘤的诊断采用CT联合MRI进行具有明显的临床价值,对于患者后续的治疗方案具有重要的指导意义,临床采用手术治疗方法效果较好。
【关键词】脑海绵状血管瘤;诊断;手术治疗;临床分析【中图分类号】R781.4 【文献标识码】A 【文章编号】2096-5249(2022)27-0081-03脑海绵状血管瘤(Cavernous Hemangioma, CH)是脑血管畸形的类型,一般的剪影血管造影技术难以发现,故又称为隐匿性血管畸形。
它并非真正的肿瘤,而是一种缺乏动脉成分的血管畸形。
它被认为是一种少见的血管畸形,可发生于脑的任何部位。
此血管瘤是由大小不等的血管窦所组成,管壁与毛细血管壁相似,多发生在大脑各叶、脑室壁、鞍区、桥小脑脚、小脑及硬脑膜上。
血管瘤大小不等,小为数毫米,大者直径可达3~4 cm,呈鲜红色或草莓状,易自发出血或血栓形成。
临床表现一般不引起症状,但位于鞍区者可出现视力与视野的改变;位于桥小脑角者与听神经瘤症状相似;有血肿形成则有各种局灶压迫症状。
但是近年来脑海绵状血管瘤的发病率呈现递增的趋势,由于脑海中的神经系统比较发达,该种疾病的病灶较多多位于脑中功能区,情况严重的会导致神经功能障碍,甚至造成患者的残疾,给患者的日常生活造成严重的影响,因此需要根据患者的临床诊断病症情况不同选择合适的手术治疗方案进行干预,提升患者的治愈率和生活质量[1]。

This guidance also applies to bioanalytical methods used for non-human pharmacology/toxicology studies and preclinical studies. For studies related to the veterinary drug approval process, this guidance applies only to blood and urine BA, BE, and PK studies.The information in this guidance generally applies to bioanalytical procedures such as gas chromatography (GC), high-pressure liquid chromatography (LC), combined GC and LC mass spectrometric (MS) procedures such as LC-MS, LC-MS-MS, GC-MS, and GC-MS-MS performed for the quantitative determination of drugs and/or metabolites in biological matricessuch as blood, serum, plasma, or urine. This guidance also applies to other bioanalytical methods, such as immunological and microbiological procedures, and to other biological matrices, such as tissue and skin samples.This guidance provides general recommendations for bioanalytical method validation. The recommendations can be adjusted or modified depending on the specific type of analytical method used. II.BACKGROUND1 This guidance has been prepared by the Biopharmaceutics Coordinating Committee in the Center for Drug Evaluation and Research (CDER) in cooperation with the Center for Veterinary Medicine (CVM) at the Food and Drug Administration.This guidance has been developed based on the deliberations of two workshops: (1) Analytical Methods Validation: Bioavailability, Bioequivalence, and Pharmacokinetic Studies (held on December 3B5, 19902 ) and (2) Bioanalytical Methods Validation C A Revisit With a Decade of Progress (held on January 12B14, 20003).Selective and sensitive analytical methods for the quantitative evaluation of drugs and their metabolites (analytes) are critical for the successful conduct of preclinical and/or biopharmaceutics and clinical pharmacology studies. Bioanalytical method validation includes all of the procedures that demonstrate that a particular method used for quantitative measurement of analytes in a given biological matrix, such as blood, plasma, serum, or urine, is reliable and reproducible for the intended use. The fundamental parameters for this validation include (1) accuracy, (2) precision, (3) selectivity, (4) sensitivity, (5) reproducibility, and (6) stability. Validation involves documenting, through the use of specific laboratory investigations, that the performance characteristics of the method are suitable and reliable for the intended analytical applications. The acceptability of analytical data corresponds directly to the criteria used to validate the method.Published methods of analysis are often modified to suit the requirements of the laboratory performing the assay. These modifications should be validated to ensure suitable performance of the analytical method. When changes are made to a previously validated method, the analyst should exercise judgment as to how much additional validation is needed. During the course of a typical drug development program, a defined bioanalytical method undergoes many modifications. The evolutionary changes to support specific studies and different levels of validation demonstrate the validity of an assay’s performance. Different types and levels of validation are defined and characterized as follows:A.Full Validation•Full validation is important when developing and implementing a bioanalytical method for the first time.•Full validation is important for a new drug entity.• A full validation of the revised assay is important if metabolites are added to an existing assay for quantification.B.Partial ValidationPartial validations are modifications of already validated bioanalytical methods. Partial validation can range from as little as one intra-assay accuracy and precision determination to a nearly full2 Workshop Report: Shah, V.P. et al., Pharmaceutical Research: 1992; 9:588-592.3 Workshop Report: Shah, V.P. et al., Pharmaceutical Research: 2000; 17:in press.validation. Typical bioanalytical method changes that fall into this category include, but are not limited to:•Bioanalytical method transfers between laboratories or analysts•Change in analytical methodology (e.g., change in detection systems)•Change in anticoagulant in harvesting biological fluid•Change in matrix within species (e.g., human plasma to human urine)•Change in sample processing procedures•Change in species within matrix (e.g., rat plasma to mouse plasma)•Change in relevant concentration range•Changes in instruments and/or software platforms•Limited sample volume (e.g., pediatric study)•Rare matrices•Selectivity demonstration of an analyte in the presence of concomitant medications•Selectivity demonstration of an analyte in the presence of specific metabolitesC.Cross-ValidationCross-validation is a comparison of validation parameters when two or more bioanalytical methods are used to generate data within the same study or across different studies. An example of cross-validation would be a situation where an original validated bioanalytical method serves as thereference and the revised bioanalytical method is the comparator. The comparisons should be done both ways.When sample analyses within a single study are conducted at more than one site or more than one laboratory, cross-validation with spiked matrix standards and subject samples should be conducted at each site or laboratory to establish interlaboratory reliability. Cross-validation should also be considered when data generated using different analytical techniques (e.g., LC-MS-MS vs.ELISA4) in different studies are included in a regulatory submission.All modifications should be assessed to determine the recommended degree of validation. The analytical laboratory conducting pharmacology/toxicology and other preclinical studies for regulatory submissions should adhere to FDA=s Good Laboratory Practices (GLPs)5 (21 CFR part 58) and to sound principles of quality assurance throughout the testing process. The bioanalytical method for human BA, BE, PK, and drug interaction studies must meet the criteria in 21 CFR 320.29. The analytical laboratory should have a written set of standard operating procedures (SOPs) to ensure a complete system of quality control and assurance. The SOPs should cover all aspects of analysis from the time the sample is collected and reaches the laboratory until the results of the analysis are reported. The SOPs also should include record keeping, security and chain of sample custody4 Enzyme linked immune sorbent assay5 For the Center for Veterinary Medicine, all bioequivalence studies are subject to Good Laboratory Practices.(accountability systems that ensure integrity of test articles), sample preparation, and analytical tools such as methods, reagents, equipment, instrumentation, and procedures for quality control and verification of results.The process by which a specific bioanalytical method is developed, validated, and used in routine sample analysis can be divided into (1) reference standard preparation, (2) bioanalytical method development and establishment of assay procedure, and (3) application of validated bioanalytical method to routine drug analysis and acceptance criteria for the analytical run and/or batch. These three processes are described in the following sections of this guidance.III.REFERENCE STANDARDAnalysis of drugs and their metabolites in a biological matrix is carried out using samples spiked with calibration (reference) standards and using quality control (QC) samples. The purity of the reference standard used to prepare spiked samples can affect study data. For this reason, an authenticated analytical reference standard of known identity and purity should be used to prepare solutions of known concentrations. If possible, the reference standard should be identical to the analyte. When this is not possible, an established chemical form (free base or acid, salt or ester) of known purity can be used. Three types of reference standards are usually used: (1) certified reference standards (e.g., USP compendial standards); (2) commercially supplied reference standards obtained from a reputable commercial source; and/or (3) other materials of documented purity custom-synthesized by an analytical laboratory or other noncommercial establishment. The source and lot number, expiration date, certificates of analyses when available, and/or internally or externally generated evidence of identity and purity should be furnished for each reference standard.IV.METHOD DEVELOPMENT: CHEMICAL ASSAYThe method development and establishment phase defines the chemical assay. The fundamental parameters for a bioanalytical method validation are accuracy, precision, selectivity, sensitivity, reproducibility, and stability. Measurements for each analyte in the biological matrix should be validated. In addition, the stability of the analyte in spiked samples should be determined. Typical method development and establishment for a bioanalytical method include determination of (1) selectivity, (2) accuracy, precision, recovery, (3) calibration curve, and (4) stability of analyte in spiked samples.A.SelectivitySelectivity is the ability of an analytical method to differentiate and quantify the analyte in thepresence of other components in the sample. For selectivity, analyses of blank samples of theappropriate biological matrix (plasma, urine, or other matrix) should be obtained from at leastsix sources. Each blank sample should be tested for interference, and selectivity should be ensured at the lower limit of quantification (LLOQ).Potential interfering substances in a biological matrix include endogenous matrix components, metabolites, decomposition products, and in the actual study, concomitant medication and other exogenous xenobiotics. If the method is intended to quantify more than one analyte, each analyte should be tested to ensure that there is no interference.B.Accuracy, Precision, and RecoveryThe accuracy of an analytical method describes the closeness of mean test results obtained by the method to the true value (concentration) of the analyte. Accuracy is determined by replicate analysis of samples containing known amounts of the analyte. Accuracy should be measured using a minimum of five determinations per concentration. A minimum of three concentrations in the range of expected concentrations is recommended. The mean value should be within 15% of the actual value except at LLOQ, where it should not deviate by more than 20%. The deviation of the mean from the true value serves as the measure of accuracy.The precision of an analytical method describes the closeness of individual measures of an analyte when the procedure is applied repeatedly to multiple aliquots of a single homogeneous volume of biological matrix. Precision should be measured using a minimum of five determinations per concentration. A minimum of three concentrations in the range of expected concentrations is recommended. The precision determined at each concentration level should not exceed 15% of the coefficient of variation (CV) except for the LLOQ, where it should not exceed 20% of the CV. Precision is further subdivided into within-run, intra-batch precision or repeatability, which assesses precision during a single analytical run, and between-run, inter-batch precision or repeatability, which measures precision with time, and may involve different analysts, equipment, reagents, and laboratories.The recovery of an analyte in an assay is the detector response obtained from an amount of the analyte added to and extracted from the biological matrix, compared to the detector response obtained for the true concentration of the pure authentic standard. Recovery pertains to the extraction efficiency of an analytical method within the limits of variability. Recovery of the analyte need not be 100%, but the extent of recovery of an analyte and of the internal standard should be consistent, precise, and reproducible. Recovery experiments should be performed by comparing the analytical results for extracted samples at three concentrations (low, medium, and high) with unextracted standards that represent 100% recovery.C.Calibration/Standard CurveA calibration (standard) curve is the relationship between instrument response and known concentrations of the analyte. A calibration curve should be generated for each analyte in thesample. A sufficient number of standards should be used to adequately define the relationship between concentration and response. A calibration curve should be prepared in the same biological matrix as the samples in the intended study by spiking the matrix with known concentrations of the analyte. The number of standards used in constructing a calibration curve will be a function of the anticipated range of analytical values and the nature of theanalyte/response relationship. Concentrations of standards should be chosen on the basis of the concentration range expected in a particular study. A calibration curve should consist of a blank sample (matrix sample processed without internal standard), a zero sample (matrix sample processed with internal standard), and six to eight non-zero samples covering the expected range, including LLOQ.1.Lower Limit of Quantification (LLOQ)The lowest standard on the calibration curve should be accepted as the limit ofquantification if the following conditions are met:C The analyte response at the LLOQ should be at least 5 times the responsecompared to blank response.C Analyte peak (response) should be identifiable, discrete, and reproducible witha precision of 20% and accuracy of 80-120%.2.Calibration Curve/Standard Curve/Concentration-ResponseThe simplest model that adequately describes the concentration-response relationshipshould be used. Selection of weighting and use of a complex regression equation should be justified. The following conditions should be met in developing a calibration curve:C#20% deviation of the LLOQ from nominal concentrationC#15% deviation of standards other than LLOQ from nominal concentrationAt least four out of six non-zero standards should meet the above criteria, including the LLOQ and the calibration standard at the highest concentration. Excluding thestandards should not change the model used.D.StabilityDrug stability in a biological fluid is a function of the storage conditions, the chemical properties of the drug, the matrix, and the container system. The stability of an analyte in a particular matrix and container system is relevant only to that matrix and container system and should not be extrapolated to other matrices and container systems. Stability procedures should evaluate the stability of the analytes during sample collection and handling, after long-term (frozen at theintended storage temperature) and short-term (bench top, room temperature) storage, and after going through freeze and thaw cycles and the analytical process. Conditions used in stability experiments should reflect situations likely to be encountered during actual sample handling and analysis. The procedure should also include an evaluation of analyte stability in stock solution.All stability determinations should use a set of samples prepared from a freshly made stock solution of the analyte in the appropriate analyte-free, interference-free biological matrix. Stock solutions of the analyte for stability evaluation should be prepared in an appropriate solvent at known concentrations.1.Freeze and Thaw StabilityAnalyte stability should be determined after three freeze and thaw cycles. At least three aliquots at each of the low and high concentrations should be stored at the intendedstorage temperature for 24 hours and thawed unassisted at room temperature. Whencompletely thawed, the samples should be refrozen for 12 to 24 hours under the sameconditions. The freeze–thaw cycle should be repeated two more times, then analyzedon the third cycle. If an analyte is unstable at the intended storage temperature, thestability sample should be frozen at -700C during the three freeze and thaw cycles.2.Short-Term Temperature StabilityThree aliquots of each of the low and high concentrations should be thawed at roomtemperature and kept at this temperature from 4 to 24 hours (based on the expectedduration that samples will be maintained at room temperature in the intended study) and analyzed.3.Long-Term StabilityThe storage time in a long-term stability evaluation should exceed the time between the date of first sample collection and the date of last sample analysis. Long-term stabilityshould be determined by storing at least three aliquots of each of the low and highconcentrations under the same conditions as the study samples. The volume of samples should be sufficient for analysis on three separate occasions. The concentrations of allthe stability samples should be compared to the mean of back-calculated values for the standards at the appropriate concentrations from the first day of long-term stabilitytesting.4.Stock Solution StabilityThe stability of stock solutions of drug and the internal standard should be evaluated at room temperature for at least 6 hours. If the stock solutions are refrigerated or frozenfor the relevant period, the stability should be documented. After completion of thedesired storage time, the stability should be tested by comparing the instrumentresponse with that of freshly prepared solutions.5.Post-Preparative StabilityThe stability of processed samples, including the resident time in the autosampler, should be determined. The stability of the drug and the internal standard should be assessedover the anticipated run time for the batch size in validation samples by determiningconcentrations on the basis of original calibration standards.Although the traditional approach of comparing analytical results for stored samples with those for freshly prepared samples has been referred to in this guidance, other statistical approaches based on confidence limits for evaluation of an analyte=s stability in abiological matrix can be used. SOPs should clearly describe the statistical method andrules used. Additional validation may include investigation of samples from dosedsubjects.E.Principles of Bioanalytical Method Validation and Establishment•The fundamental parameters to ensure the acceptability of the performance of a bioanalytical method validation are accuracy, precision, selectivity, sensitivity,reproducibility, and stability.• A specific, detailed description of the bioanalytical method should be written. This can be in the form of a protocol, study plan, report, and/or SOP.•Each step in the method should be investigated to determine the extent to which environmental, matrix, material, or procedural variables can affect the estimation of analyte in the matrix from the time of collection of the material up to and including the time ofanalysis.•It may be important to consider the variability of the matrix due to the physiological nature of the sample. In the case of LC-MS-MS-based procedures, appropriate steps should be taken to ensure the lack of matrix effects throughout the application of the method,especially if the nature of the matrix changes from the matrix used during method validation.• A bioanalytical method should be validated for the intended use or application. All experiments used to make claims or draw conclusions about the validity of the methodshould be presented in a report (method validation report).•Whenever possible, the same biological matrix as the matrix in the intended samples should be used for validation purposes. (For tissues of limited availability, such as bone marrow, physiologically appropriate proxy matrices can be substituted.)•The stability of the analyte (drug and/or metabolite) in the matrix during the collection process and the sample storage period should be assessed, preferably prior to sampleanalysis.•For compounds with potentially labile metabolites, the stability of analyte in matrix from dosed subjects (or species) should be confirmed.•The accuracy, precision, reproducibility, response function, and selectivity of the method for endogenous substances, metabolites, and known degradation products should beestablished for the biological matrix. For selectivity, there should be evidence that thesubstance being quantified is the intended analyte.•The concentration range over which the analyte will be determined should be defined in the bioanalytical method, based on evaluation of actual standard samples over the range,including their statistical variation. This defines the standard curve.• A sufficient number of standards should be used to adequately define the relationship between concentration and response. The relationship between response and concentration should be demonstrated to be continuous and reproducible. The number of standards used should be a function of the dynamic range and nature of the concentration-responserelationship. In many cases, six to eight concentrations (excluding blank values) can define the standard curve. More standard concentrations may be recommended for nonlinear than for linear relationships.•The ability to dilute samples originally above the upper limit of the standard curve should be demonstrated by accuracy and precision parameters in the validation.•In consideration of high throughput analyses, including but not limited to multiplexing, multicolumn, and parallel systems, sufficient QC samples should be used to ensure control of the assay. The number of QC samples to ensure proper control of the assay should be determined based on the run size. The placement of QC samples should be judiciously considered in the run.•For a bioanalytical method to be considered valid, specific acceptance criteria should be set in advance and achieved for accuracy and precision for the validation of QC samples over the range of the standards.F.Specific Recommendations for Method Validation•The matrix-based standard curve should consist of a minimum of six standard points, excluding blanks, using single or replicate samples. The standard curve should cover the entire range of expected concentrations.•Standard curve fitting is determined by applying the simplest model that adequately describes the concentration-response relationship using appropriate weighting and statistical tests for goodness of fit.•LLOQ is the lowest concentration of the standard curve that can be measured with acceptable accuracy and precision. The LLOQ should be established using at least five samples independent of standards and determining the coefficient of variation and/orappropriate confidence interval. The LLOQ should serve as the lowest concentration on the standard curve and should not be confused with the limit of detection and/or the low QC sample. The highest standard will define the upper limit of quantification (ULOQ) of an analytical method.•For validation of the bioanalytical method, accuracy and precision should be determined using a minimum of five determinations per concentration level (excluding blank samples).The mean value should be within ±15% of the theoretical value, except at LLOQ, where it should not deviate by more than ±20%. The precision around the mean value should not exceed 15% of the CV, except for LLOQ, where it should not exceed 20% of the CV.Other methods of assessing accuracy and precision that meet these limits may be equally acceptable.•The accuracy and precision with which known concentrations of analyte in biological matrix can be determined should be demonstrated. This can be accomplished by analysis ofreplicate sets of analyte samples of known concentrations C QC samples C from anequivalent biological matrix. At a minimum, three concentrations representing the entire range of the standard curve should be studied: one within 3x the lower limit of quantification (LLOQ) (low QC sample), one near the center (middle QC), and one near the upperboundary of the standard curve (high QC).•Reported method validation data and the determination of accuracy and precision should include all outliers; however, calculations of accuracy and precision excluding values that are statistically determined as outliers can also be reported.•The stability of the analyte in biological matrix at intended storage temperatures should be established. The influence of freeze-thaw cycles (a minimum of three cycles at twoconcentrations in triplicate) should be studied.•The stability of the analyte in matrix at ambient temperature should be evaluated over a time period equal to the typical sample preparation, sample handling, and analytical run times.•Reinjection reproducibility should be evaluated to determine if an analytical run could be reanalyzed in the case of instrument failure.•The specificity of the assay methodology should be established using a minimum of six independent sources of the same matrix. For hyphenated mass spectrometry-basedmethods, however, testing six independent matrices for interference may not be important.In the case of LC-MS and LC-MS-MS-based procedures, matrix effects should beinvestigated to ensure that precision, selectivity, and sensitivity will not be compromised.Method selectivity should be evaluated during method development and throughout methodvalidation and can continue throughout application of the method to actual study samples.•Acceptance/rejection criteria for spiked, matrix-based calibration standards and validation QC samples should be based on the nominal (theoretical) concentration of analytes.Specific criteria can be set up in advance and achieved for accuracy and precision over therange of the standards, if so desired.V.METHOD DEVELOPMENT: MICROBIOLOGICAL AND LIGAND-BINDING ASSAYSMany of the bioanalytical validation parameters and principles discussed above are also applicable to microbiological and ligand-binding assays. However, these assays possess some unique characteristics that should be considered during method validation.A.Selectivity IssuesAs with chromatographic methods, microbiological and ligand-binding assays should be shown to be selective for the analyte. The following recommendations for dealing with two selectivity issues should be considered:1.Interference From Substances Physiochemically Similar to the Analyte•Cross-reactivity of metabolites, concomitant medications, or endogenouscompounds should be evaluated individually and in combination with the analyteof interest.•When possible, the immunoassay should be compared with a validated reference method (such as LC-MS) using incurred samples and predetermined criteria foragreement of accuracy of immunoassay and reference method.。
